This document pertains to Compaq desktop PCs.
Use this document to identify your Compaq Presario Desktop computer. If you have a Presario Notebook PC, see Compaq Presario Notebooks - Locating the Model and Serial Numbers .
CAUTION:Installing incorrect drivers or following incorrect troubleshooting procedures could damage your computer. Many Compaq Presarios are identified on the front of the computer by a series number rather than the actual model number . For example, your Presario may be labeled with 5000 on the front of the case, but it is actually part of a 5000 series PC. The correct model number may be 5WV283. If you have a 4000, 5000, 6000, 7000, or 8000 series PC, verify that you know the correct model or product number before using support information from the Customer Care web site.
NOTE:Some desktop computers are sold in a bundle with a monitor, scanner, and/or printer. The bundle of products is identified by a "-b " after the model name. To find information for the desktop computer inside the bundle, search for the model name without the “-b ”. For example, to find information on the SR1913wm-b , search HP's Web site for SR1913wm . To find information about another product in the bundle, such as a printer, look for its model name on a label adhered to the body of the product.
For more information on a given step, click the heading or the accompanying plus (+) sign to expand the information.

The model number or equivalent might be found on an identification label on the outside of the case. On some models the label might be hidden behind the CD storage door or behind the door that covers the CD drives.
When searching HP's Website for your exact model, you can also use the Product number , Prod # , T Code , or System number .
